I MPROVEMENT IN WHIFFLETREES.

Specification forming part of Letters Patent No. 58,759, dated October 16, 1866.

giving it movement in the movable clevis at-.

tached. Fig. 2 represents the top view of the clevis, into which the single-tree is set, being secured to the main bar by a pin or bolt, as shown in Fig. 3. Fig. 3represents a side "iew of the clevis, with the two pins or bolts which hold the single-tree to the clcvis and the clevis to the main bar. Fig. at represents the full view of the double whiftietree with improvements attached, A being the single-tree, and B the clevis in which it works.

I propose to construct the main bar of oak or other suitable wood, the single-tree and clevis of iron or other hard material, the single-tree to play on bolt through clevis, the clevis to play on bolt attached to center of main bar or tree.

I claim as the distinctive feature of this improvement The application of a combination singletree and clevis to the center of double whiffietrees, whereby a direct and equalized strain is brought to bear on the center of the carriage, so that by this application or combination of movement the traces shall have free play, an equal and steady draft imparted to the center of the carriage, and the present continual leverage of one horse against the other obviated.
